Question

looking at a cell under a microscope, you note that it is a prokaryote. how do you know? a. the cell lacks a cell membrane. b. the cell lacks genetic material. c. the cell lacks cytoplasm. d. the cell lacks a nucleus.

Explanation:

Prokaryotic cells are defined by the absence of a membrane-bound nucleus, unlike eukaryotic cells which have a nucleus to enclose their genetic material. All cells (prokaryotic and eukaryotic) have a cell membrane, genetic material, and cytoplasm, so options A, B, and C are incorrect.

Answer:

D. The cell lacks a nucleus.
